The Orb is a British electronic music band known for pioneering the genre of ambient house. The Orb is heavily influenced by dub music, and much of their later output has been in the electronic dub category, more so than ambient house.
The group was formed in 1988 by Dr. Alex Paterson (full name Duncan Robert Alex Paterson) and Jimmy Cauty (one half of The Justified Ancients of Mu Mu and later The KLF). The Orb's first release was the acid house anthem "Tripping on Sunshine".
